.MEANS FOR HERMETICALLY CLOSING RECEPTACLES.

SPECIFICATION forming part of Letters Patent No. 495,775, dated April18, 1893. Application filed September 28, 1892. Serial No. 447,128. (Nomodel.) Patented in France January 16, 1891, No. 210,827.

To all whom it may concern.-

' Be it known that 1, Louis ARTHUR Bon- NAMY, a citizen of the Republicof France, residing at 18 Queenhithe, in the city of London, England,have invented an Improved System of and Means for I-Iermetically ClosingReceptacles, (for which I have obtained a patent in France, datedJanuary 16, 1891, No. 210,827,) of,which the following is a speci'ficat-ion.

My invention relates to a new system and means for hermetically closingreceptacles especially such as are intended for preserved foods andthelike.

My object is to provide a simple and easily removed closure which willeffectually prevent the access of air into the receptacles, and by whichno injurious surface or surfaces will be in contact with the contents.

The accompanying drawings illustrate the preferred forms.

Figure 1 is a section of a cover; Fig. 2 a section of a receptacle; Fig.3 a section of compressible ring; Fig. 4 a part plan of ring; Fig. 5 aperspective view of clasp open; Fig. 6 a section showing the parts inposition when closure is made, and Fig. 7 an elevation of same.

A is the cover with a projecting flange, and of such shape as to projectfora suitable distance into the receptacle B which has a projectingcollar 1) about its mouth.

0 is the compressible ring and D the clasp.

The upper surface of the outer part of flange a and the lower surface ofthe outer part of collar 1) are both slightly beveled as shown. In thelower face of flange a annular grooves a are formed and a shallow rim 1)is formed upon collar b and a corresponding groove a in flange a;outside of which in flangeais formed the annular groove 64', preferablywith concentric ribs and inclined upward inwardly as shown in Figs. 1and 6.

The surface Z2 of collar (1 is left flat or approximately so. The ring 0is of rubber or other compressible material and is covered on its innerside and for part of its width,as illustrated, with tin foil or othernon-injurione medium 0.

The clasp D, Fig. 5, is made of tin plate or other resilient metal andhas at its top and base inwardly projecting rims or flanges cl extendingthe full length of the clasp, when closed. They are cut away at one ormore points d, so as to enable the clasp to be read"- ily bent back andopened. One of the free ends has a plain extension E, in which. is cut aslot 6, and near the other end of D is stamped or formed a tongue 6.

To effect the hermetic closure, the ring O is first placed on thesurface b of collar 1) or in the groove 01, of flange a and the cover Ais then put on the receptacle B, the parts fitting Then pressure isapplied by a lever, clamp, or other suitable and convenient means to thecover A, sufflcient to compress the ring 0, and while under pressure theclasp. D is presented half opened and fitted around the flange a andcollar b, so that its rims d, d grip and hold upon the beveled surfacesthereof. Then the clasp is firmly drawn or pressed together and thetongue 6' inserted through slot-e in E, and bent backward as shown inFig. 7, effectually and hermetically closing the receptacle. The

tin foil 0 also effectually prevents the 'contents of the receptaclecoming in contact with the rubber or other substance of which it ismade. To open the receptacle it is only necessary to bend back andunhook the tongue e from the slot 6 when the clasp and cover may beeasily removed and access to the contents obtained.

What I claim, and desire to secure by Let-' ters Patent, is- I Incombination, the jar having a rim with a plain bearing face and a flangeb at the inner edge thereof, the cover having a portion to depend withinthe flange b and a groove a the said cover having also a rim with itsunder surface inclining upwardly toward the groove a and provided withgrooves, the packing between the inclined grooved face of the cover rimand the flat face of the jar rim the .tin foil covering the inner edgeof the packing and part of its upper and lower bearing surface and theclasp for embracing the rims,

' substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
